TCL Thread clarification

TCL Thread clarification

TCL Thread clarification

HI, I am Dhinesh,

I want some clarification in TCL Thread, I am new to the thread concept,
I am using TCL activate 8.6 version, when i run the below code in TK console, puts "Thread [thread::id] says hello" this line is not printing on the console. But if i use Sh mode it works fine, can any one help me to understand this.

package require Thread
puts "*** I'm thread [thread::id]"
# Create 3 threads
for {set thread 1} {$thread <= 3} {incr thread} {
set id [thread::create {
# Print a hello message 3 times, waiting
# a random amount of time between messages
for {set i 1} {$i <= 3} {incr i} {
after [expr { int(500*rand()) }]
puts "Thread [thread::id] says hello"
}] ;# thread::create
puts "*** Started thread $id"
} ;# for
puts "*** Existing threads: [thread::names]"
# Wait until all other threads are finished
while {[llength [thread::names]] > 1} {
after 500
puts "*** That's all, folks!"
